Provide release using peripheral access crate stm32f3 0.13.2

[sirhcel]

There is an issue with stm32f3 0.13.0 and before which requires to use unsafe code for sending serial data via a USART (stm32-rs/stm32-rs#558). This currently requires UART example code in the Discovery Book to use unsafe (rust-embedded/discovery#267 (comment)) which does not play nice with an introduction to Embedded Rust.

Could you please release a version of this crate which uses stm32f3 0.13.2 (fixing the USART issue and stm32-rs/stm32-rs#568) so that we can make the Discovery Book examples safe again? I would prefer a release based on the current master as it already contains the new naming scheme pac for the re-exported PAC.

Thanks for the heads up. This is a good motivation to actually release a new version.

I'll plan to release a new version soon ish. I've took the time of the weekend to bring #212 close to the finish line. This has to be cleaned up and merged. If this is done I'll plan to release a newer version.
